Question

answer this ...........​

Answer 1

99x+101y=499-----(1)

101x+99y=501------(2)

Since the LCM of 99 and 101 is 9999, we need multiply (1) by

101 and (2) by 99,

9999x+10201y=50399------(3)

9999x+9801y=49599------(4)

Subtracting (4) from (3),

400y=800

➡y=2

Substituting y=2 in (1),

99x+101(2)=499

99x=499-202

99x=297

➡x=3

Hence,

↪x=3

↪y=2
